I can only ask you to vote to not reduce the free OneDrive storage: http://onedrive.uservoice.com/forums/262982-onedrive/suggestions/10524099-give-us-back-our-storage
I really hope, MS will think this over. Other companies (like Google) offer 15 GB of storage for free and unlimited storage for photos. At the Moment my „camera roll“ contains photos of about 8 GB…if this will be limited to 5 GB I guess I will have to move these photos to another cloud service.
Next problem: Windows Phone only allows to configure OneDrive for an automatic photo upload…so maybe you have to manuylly download your photos to save them to a local drive and upload them to another cloud service? 🙁
